Product Description:

The MDD090C-N-020-N2L-130PA1 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. It is designed for use with digital drive controllers and converts stator current into precise rotary motion for industrial positioning axes, packaging lines, and material-handling stations. This operating principle supports accurate acceleration, deceleration, and controlled holding behavior when the motor is paired with a compatible drive. Because it is a synchronous motor, rotor motion remains directly coordinated with the commanded electrical field, which helps preserve positioning accuracy during repeated indexing cycles. Its mechanical layout, feedback interface, and shaft arrangement are matched to compatible drive modules so the motor can maintain closed-loop speed and torque control in automated equipment.

The motor has a nominal speed of 2000 rpm, which is the top rotational velocity under rated load. At standstill, the electromagnetic system can deliver 10.4 Nm continuously, allowing the axis to support steady process forces without overheating during normal operation. Power and feedback leads exit on Side A, which helps keep cable routing consistent when several motors are mounted on a common machine wall. A circular multi-pin connector carries the phase conductors, protective earth, and encoder signals in one locked interface, reducing the number of separate connection points at the housing. This layout also helps simplify access around the rear of the machine.

The motor includes a blocking brake that applies 6.5 Nm when power is removed, which helps hold the shaft in vertical or suspended-axis applications. Rotor position is returned through Digital servo feedback (DSF), providing high-resolution position information to the controller and supporting synchronized commutation across the speed range. The flange has a centering recess of 130 mm for accurate alignment with couplings or gearboxes during installation. The output shaft uses a keyway for positive torque transmission, and a shaft seal helps keep lubricant in place while limiting contaminant entry. The motor also uses standard balancing, a C-length stator section, a size 090 housing, and a single-ended shaft.
